A recirculating powder lubricant delivery system having improved oxidative stability and a lubricant therefor where the lubricant is a solid lubricant selected from a group of molybdenum disulfide, graphite and graphite fluoride, and wherein the solid lubricant is microencapsulated from an aqueous suspension of an alkali metal silicate containing a water soluble phosphate.

Thermally and oxidatively stable solid lubricants

A controlled release composition of biologically active materials is prepared by reacting a biologically active agent, aqueous polyhydroxy polymer, inorganic salt, and optional filler(s), drying the product and then grinding the product to the desire particle size. The product is then used, for example, for controlling pests.

Polyhydroxy polymer delivery systems

An article for storage and transport of biogenic fluids such as blood, blood fractions, intravenous feeding solutions and liquid phase-delivered drugs is formed of an additive-free uncharged thermoplastic polymer of vinylidene fluoride copolymerized with a monomer.

A flame retardant composition is prepared by reacting chloral with a nitrogen compound having the formula: ##STR1## wherein: (a) X= ##STR2## or, --SO.sub.2 --; (b) Z is selected from O or S;

Process for reacting chloral with nitrogen compositions

Microcapsules comprising a core containing a water-soluble salt of a medicament and a polymer, e.g., the salt of a medicament containing an amine-group and a carboxyl group containing polymer, and a sheath of a water-insoluble film forming polymer, e.g., ethyl cellulose, the method of their production and their administration are disclosed. The microcapsules can be formed by dispersing an aqueous solution of the medicament-polymer salt in a water-immiscible solvent solution of a water-insoluble film forming polymer, adding another water-immiscible solvent which is a non-solvent for the water-insoluble polymer, and collected the microcapsules. The microcapsules are administered orally to animals and exhibit substantially slower release rates and more uniform release rates in stomach acids than the corresponding unencapsulated salts or encapsulated non-polymeric salts.

Microcapsules containing medicament-polymer salt having a

Phosphinic acids of the formula ##STR1## wherein (A) R is ##STR2## (1) X is 3-phenylene or 4-phenylene, and (2) Y is a direct bond, ##STR3## (B) R' is R, lower alkyl of from 1 to 3 carbon atoms, 4-biphenylyl, or phenyl. These acids are neutralized with an equivalent amount of alkali metal carbonates to form alkali metal salts which react with ZnCl.sub.2 to form polymers having high thermal stability.
